THOMAS AMPHLETI, OF KIEV, RUSSIA.

WATER-GAGE AND ALARM.

SPECIFICATION forming part of Letters Patent N o. 256,264, dated April 11, 1882.

Application iled November 2, 1881. (No model.) Patented in l rmany May 27, 1880, in France August 2, 1880, in Belgium August 4, 1880, and in Austria September 27, 1880.

To all whom it may concern:

Be it known that I, THOMAS AMPHLETT, a subject of the Empire of Germany, residing at Kiev, in the Empire of Russia, have invented new and useful Improvements in Water-Gages, ot' which thegfollowing is a specification.

This invention relates to certain improvements in water-gages and alarms connected therewith, the specilic construction which constitutes my invention being fully set forth in the following specication.

In the accompanying drawings, Figure 1 shows a side elevation, Fig. 2 a vertical section, and Fig. 3 a horizontal section after line :c a', of my improved water-gage.

Similar letters indicate corresponding parts.

This gage principally consists of a oat, A, made of sheet metal, connected at its top to a vertical rod terminating in a rack, B. rhis rack gears into a cog-segment, C, fast upon a spindle, D, provided with a valvefseat, K,.Fig. 3, by means ot' which it passes steam-tight through the front side of a case or cylinder, H, screwed upon the boiler, and through a dial-disk, J, fastened onto said case H. On the end projecting on the outside of this dial the spindle D supports an indicator-hand, Z, intended to show by marks upon said dial the diierent levels of water in a boiler. With the rising and falling of the water the float must rise and fall also, and with it rack B, acting upon segment (l, which turns spindle D and hand Z to the right or left, according to rise or fall, so that the water-level can always be told by the position of the hand to the marks on the dial.

The float-'rod is provided with E, Fig. 2, so adjusted that they will, one on reaching its highest, the other on reaching its lowest, point, move one of the two bell-crank levers F. One end of each of these levers is connected with a small valve, n, While the other terminates in a fork, through which the tloatrod passes. When, in case of too high or too low water, one of the collars E touches the upper or lower lever, F, it opens the respective valve, and a steamwhistle, w, connected with two collars,

it is put in action. the two lever-'arms the valves c closed.

For the cog-segment of the arrangement just described a plain segment without any teeth may be substituted, over whose circumference two light chains, wires, or strips of metal are passed, the ends ot' which are connected with the segment and with the floatrod, respectively-that is, the one chain, wire, or strip is fastened with one end to the top end of the ioat-rod and with-the other to the opposite (lower) end ofthe segment, and vice versa, as shown in Fig. 4 of the drawings.

In place of a segment, a crank or lever, as shown in Fig.5,may be used to the same ei'ect.

The principal advantages of this water gage or indicator over the common glass gages and the magnetic float-gages are: the actuating of the alarm-whistle with the greatest precision, and permitting of a very exact control of the water-level even at a distance from the boiler. The latter object ma easily be attained by lengthening the spindle D to any desired distance-as, forinstance, to engine-room oroftice, where a dial may be fixed, so as to permit observing the water-level from there without having to go to the boiler.

What I claim as new, and desire to secure by Letters Patent, is-

In water-gages, the combination, with a oat, of a steam-tight case or cylinder fast upon and communicating with the boiler, a spindle, D, with hand Z, a dial, J, a rod extending from theiioat and connected to the spindle D, two collars, E, mounted on this rod, bell-crank le,- vers F, valves c, and whistles w, all for the purpose, and substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

G is a spring connecting for the purpose of keeping THOMAS AMPHLETT.
